Undo working copy modifications of one file in Git? mongodb|MONGODB and refer to to oc rsync. A Red Hat training course is available for OpenShift Container Platform. directory or a pod directory. I didnt mention this before, but I tried to keep it the installation steps as simple as possible, as this is a very interesting approach (GA since 3.11 and above). If rsync is not found locally or in the remote container, then a tar archive Overview. We are going to use one of the two types of Admission Webhooks, the Validating admission webhooks, that allow for the use of validating webhooks to enforce custom admission policies. For more information on access modes, see the Kubernetes persistent volume documentation. You should receive some output similar to this: For the application being used, this has created a database file like this: 40 -rw-r--r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. When using the --watch option, the behavior is effectively the same as Part one: Manually Copying Files Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. Before starting, make sure that you're logged into your OpenShift cluster through the terminal and have created a project. example, oc rsync creates the destination directory if it does not exist and To ensure only the contents of the directory on the container are copied, and not the directory itself, suffix the remote directory with /.. The --delete option ensures that the resulting directories will match exactly, with directories/files in the local directory which are not found in the pod being deleted. What are examples of software that may be seriously affected by a time jump? Making statements based on opinion; back them up with references or personal experience. The --strategy=tar option indicates to use tar to copy the files rather than rsync. The result will be a running container. In the example I am looking at they use NFS PV and it is quite simple as I can access the NFS file system associated with a PV and I can add files to it. When copying files to the container, it's required that the directory into which files are being copied exists, and that it's writable to the user or group that's running the container. 3.1. In the above command, the --no-perms option is also used, because the target directory in the container, although writable by the group that the container is run as, is owned by a different user. the claim is paired with a volume that generally matches your request. Instead a cluster administrator would provision a network resource like a Google Compute Engine persistent disk, an NFS share, or an Amazon Elastic Block Store volume. will be created locally and sent to the container where tar will be used to To try it and our other tutorials without needing to install OpenShift, visit https://learn.openshift.com. alternative to running oc rsync. To create an interactive shell within the same container running the application, you can use the oc rsh command, supplying it the environment variable holding the name of the pod. A Persistent Volume (PV) enables you to keep state outside of your Pods, which means that your applications won't lose valuable data when a Pod fails or even your entire cluster. name: Just as with standard rsync, if the directory name ends in a path separator (/), . In this post, well cover manually copying files into and out of a container. MySQL is used in the example below. Copying files to or from an OpenShift Container Platform container You can use the CLI to copy local files to or from a remote directory in a container using the rsync command. Thanks for contributing an answer to Stack Overflow! Migrate between different storage types (NFS/NAS to iSCSI/SAN, for example). Individual files are not supported. oc cp /:/cepfs/.. example : This worked without needing to take any further actions as the Apache HTTPD server being used to host static files automatically detects the presence of a new file in the directory. hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, You can use the CLI to copy local files to or from a remote directory in a container. As already noted, it's not possible to copy a single file this way, so we indicate that the current directory should be copied, but use the --exclude=* option to first say that all files should be ignored when performing the copy. It can also be used to copy source code changes into a running pod for development debugging, when the running pod supports hot reload of source files. Again, monitor the progress of the deployment so we know when it's complete, by running: To confirm that the persistent volume claim was successful, you can run: With the dummy application now running, and with the persistent volume mounted, find the name of the pod for the running application with the following command: This will return something like this, with your unique pod name that youll need to use in the following commands: We can now copy any files into the persistent volume, using the /mnt directory (where we mounted the persistent volume) as the target. This OpenShift Commons Gathering will be held live in Amsterdam, The Netherlands and broadcast live to regional watch parties around the globe. When working with oc rsync, note the following: The oc rsync command uses the local rsync tool if present on the client PersistentVolumeClaim to bind to, you can specify the PV in your PVC using the use with the oc rsync command. Mount the PV in a different pod, and "oc cp" the files in, or "oc rsh " and curl/wget/scp from inside the pod to the local volume mount. It can also be used to copy source code changes into a running pod for development debugging, when the running pod supports hot reload of source files. Deploy container and mount volume - CLI. Describing best practices for backing up open files and databases is out of the scope of this article, but we tend to use the databases native tools for backing up & restoring (e.g., mysqldump, pg_dump, etc.). claim with the given name in the same namespace as the pod, then uses the claim If there are additional files in the target directory which don't exist in the container, those files will be left as is. First, we create a robots.txt file in our local directory which contains: For the web application being used, it hosts static files out of the htdocs subdirectory of the application source code. request for a resource with specific attributes, such as storage size. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Kubernetes provides an API to separate storage from computation, i.e., a pod can perform computations while the files in use are stored on a separate resource. rapidly changing file system does not result in continuous synchronization You can see this procedure in the code. Would the reflected sun's radiation melt ice in LEO? environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its Part one covered manually copying files into and out of a container. To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . In the case that you wish to use a standard rsync command line option which is Therefore, you can control the behavior via the same flags used your claim so that nobody elses claim can bind to it before yours does. We mount the persistent volume at /mnt inside of the container, which is the traditional directory used in Linux systems for temporarily mounting a volume. Adjust OpenShift Security Context Constraints (SCCs) once, before making your first backup: Add the adjusted SCC from step 1 to the ServiceAccount created by the template: A normal cluster user could use the Service Account, Now, to configure/enable our custom webhook you can use the following yaml, You dont need to change the SCC object (, Avoid losing all those assignments if you update the SCC. The backup script contains a little magic especially for this case: Setting the sticky bit on the sed executable makes the effective UID of sed processes that of the /usr/bin/sed executable files owner -- in this case, root -- rather than that of the user who executed it. At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. A complete example of this can be found in the OpenShift documentation. file system changes, and synchronizes changes when they occur. copy will fail. File storage, also called file-level or file-based storage, stores data in a hierarchical structure. Find centralized, trusted content and collaborate around the technologies you use most. to a new database containers persistent volume directory. In a production cluster, you would not use hostPath. field. is created locally and sent to the container where the tar utility is used to If such a PV with that name exists and is Available, the PV and This is a useful tool for copying database archives to and from your pods for backup and restore purposes. PVC will be bound regardless of whether the PV satisfies the PVCs label This will cause a new deployment of our dummy application, this time with the persistent volume mounted. Price / licenses: For some of the solutions I checked you need to purchase a license. This article focuses on backing up, migrating, and restoring storage layer entities: Kubernetes PVCs and the Persistent Volumes that back them. Sign up for the free trial of OpenShift Online. Here we find, for example, databases with their own tools and procedures to create application-consistent backups. Do you have an OpenShift Online account? Persistent Volume Claim Object Definition, Example 1. You might call this an archive PV. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. The --no-perms option ensures that no attempt is made to transfer permissions, which can fail if remote directories are not owned by the user that the container runs as. use with the oc rsync command. The core component is a pod based on a custom container image. selector-label Part two went into live synchronization. We have been able to see during the reading of all the chapters how I faced the challenge to implement backup-restore / migration capabilities in an OpenShift cluster with my artisanal solution. only the contents of the directory are copied to the destination. The docker image doesn't need to run as root, but it requires a small but important trick before it is executed: You must have an OCP cluster running OpenShift version 3.9 or greater to provide the required, You must build the BackupEr container image and push it to your container registry, or use the custom templates, or simply. You can see an example by reviewing the backup-block template. oc rsync ./local/dir :/remote/dir --strategy=tar: Copy the directory to the remote directory in the pod. View this by running: Now that we have a running application, we next need to claim a persistent volume and mount it against our dummy application. If Step 1 - Creating a project The first thing we need to do is create a project where we can deploy the application that we will be working with. secretKey is a key name within that secret. Launching the CI/CD and R Collectives and community editing features for Standard concise way to copy a file in Java? Finally, in part three, well cover copying files into a new persistent volume. To upload the robots.txt file, we run: oc rsync . oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --type pvc --claim-size=1G --mount-path /mnt. ensure your claim gets bound to the volume you want, you must ensure that both The other layer is the underlying storage. You'll be using just the oc command line tool. The existing options I checked didnt fit my needs for a variety of reasons: For this reason I decided to implement a homemade solution. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Support for copying local files to or from a container is built into the CLI. There's no reason to wait. remote shell program to enable it to connect to the remote pod, and are an The API introduces 2 types of resources: projects: A PersistentVolume is a specific resource. Fire up a terminal on the pod and use your favourite tools like ls and df to list files or see stats of the volume usage. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. If October 5, 2017 | by hferentschik added a commit to hferentschik/minishift that referenced this issue Adding method to wait for completion of persisten 4404475 This means that, although the files can be added to the directory, permissions on existing directories cannot be changed. directory or a pod directory. extract the files. Manage persistent volume access in Kubernetes | Red Hat Developer You are here Read developer tutorials and download Red Hat software for cloud application development. AWS EBS, Further to create the persistent volume (PV) and storage class to be used for the containers. might be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH volume binding before resorting to setting claimRefs on behalf of users. If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . I decided to dedicate a couple of lines to this.The advantage of this approach instead to using traditional SCC assignment (oc adm policy add-scc-to-) is that: You only have to worry about to manage rolebindings. the directory does not exist, but rsync is used for copy, the directory is The ability to set claimRefs is a temporary workaround for the described use extract the files. To illustrate the process for copying a single file, consider the case where you deployed a website but forgot to include a robots.txt file, and need to quickly add one to stop a web robot which is crawling your site. Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. The example assumes an existing database container. You have a few options. PersistentVolume objects from sources such as GCE Persistent Disk, AWS The only constraint here is to deploy the BackupEr pod on the same OpenShift cluster node with the pod/PVC you want to back up. Persistent volumes (PVs) and persistent volume claims (PVCs) can share volumes across a single project. | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . To create a dummy application for this purpose, run this command: oc run dummy --image centos/httpd-24-centos7. The PVs and PVCs where you For example: The architecture is relatively simple. using the rsync command. If you already have an existing persistent volume claim, as we now do, you could mount the existing claimed volume against the dummy application instead. You can find a summary of the key commands covered below. Check that all the resource objects have been deleted: Although we've deleted the dummy application, the persistent volume claim still exists, and can later be mounted against the actual application to which the data belongs. You can use the CLI to copy local files to or from a remote directory in a container Permissions on directories and files should be set as part of the process of building the image. Clash between mismath's \C and babel with russian, Story Identification: Nanomachines Building Cities. In the next sections, I will demonstrate the usefulness of OpenShift's persistent volume framework by deploying a MySQL database, first without and then with persistent volume storage. This pod is responsible for running the backup script. NOTE: The communication between your cluster/API and your Webhook must be secured and with trusteable SSL certificates. namespace specified in claimRef. RBD, Unlike when copying from the container to the local machine, there's no form for copying a single file. move to the folder from which you want to copy the file. Admission webhooks call webhook servers to either mutate pods upon creation --such as to inject labels-- or to validate specific aspects of the pod configuration during the admission process. Second, you can access it from the pod that uses the PersistentVolumeClaim. Is storage in Openshift Online free tier actually persistent? Make sure that the storageClassName matches the storage class created in the last step: YAML apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-azurefile spec: accessModes: - ReadWriteMany storageClassName: my-azurefile resources: requests: storage: 100Gi Note iSCSI, and 40 -rw-rw-r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. Why must a product of symmetric random variables be symmetric? Now create a file named azure-file-pvc.yaml and copy in the following YAML. kubectl cp my-file my-pod:my-file -c my-container-name. kubectl cp <file-spec-src> <file-spec-dest>. Create the vault-database SecretProviderClass. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. Use the appropriate commands to restore the database in the new database On the NFS server, identify the location of the source volume as well as location used by a target volume, and use normal file system copy mechanisms.
